<p>Castro is 78 years old and probably won't last too many more years. What do you think will happen once he is out of power? Here are some options that come to mind:</p>
<p>1- nothing, becuase Castro may have adequately planned for his succession and the US is full of a bunch of tough talkers but wimps.
2- nothing, becasue Cubans living in America will realize they prefer American wealth to Cuban poverty.
3- Florida cubans mount an independent an unauthorized attack on Cuba that results in a re-taking of the island for freedom.
4- The US uses its troops located in Cuba to take over the country and implement democracy.
5- The US takes the matter before the United Nations and while the UN debates the issue and ultimately decides to do nothing, thousands of Cubans die in a civil war.
6- something else that you think will happen.</p>
